Francesco Lo Monaco: Your Smartwatch Might Already Know When Your Heart Will Give up Before You Do
Francesco Lo Monaco, Cardiologist and Founder of The National Heart Clinic, posted on LinkedIn:
”Your smartwatch might already know when your heart will give up before you do.
It’s not science fiction, it’s physiology.
Every day, your watch quietly measures the data that predicts how efficiently your heart is aging… long before any symptom appears.
Most people only check their steps or calories.
But the real story, the one that reveals how long (and how well) you’ll live, is hidden in the heart data you rarely look at.
Your smartwatch isn’t just tracking “fitness.”
It’s tracking resilience, recovery, and the subtle signs of heart aging.
Here’s what matters most:
→ Resting Heart Rate (RHR)
Under 60 bpm is ideal (around 50 is even better).
Evidence suggests a 16% increased risk of death for every 10 bpm increase in resting heart rate beyond 60 bpm.
A lower RHR means your heart doesn’t have to work as hard, that’s a sign of efficiency, not weakness.
→ Heart Rate per Step (HRPS)
Almost no one tracks this yet, but it’s a game changer.
The fewer beats per step, the more efficient your heart is.
If it starts rising over time, it can flag early trouble months before symptoms appear.
→ Heart Rate Variability (HRV)
A direct window into your adaptability and recovery.
Higher HRV = better stress resilience, improved longevity, and a healthier nervous system.
→ VO₂ Max
Think of this as your heart’s horsepower.
The higher it is, the stronger your cardiovascular foundation – and the longer you’re likely to live.
→ Pulse Pressure (the gap between top and bottom blood pressure)
Keep it under 40 mmHg.
A widening gap can signal stiff arteries, one of the earliest signs of vascular aging.
Longevity isn’t about luck or genetics, it’s about awareness.
The data is already on your wrist; we just need to learn how to interpret it.”
